phpMyAdmn work during the fortieth week

The fortieth week of work was mostly spent on fixing the bugs in the upcoming 4.5 version. 

While implementing the export templates I noticed that lock_table directive is not repopulated similar to other directive when back button is click and this was fixed. Further, quite a lot of the links to new system variables in phpMyAdmin's Variables page  was missing, and these were also added. Bug #4854 was fixed allowing users to use multiple servers in parallel. Earlier this was not possible and a series of fixes such as introducing IV per server finally led to this fix.

Here is the list of bugs fixed and investigated.

Among feature improvements, the most notable one is the use of native tabs in server plugin page in place of the jQuery tabs. Additionally, the process list was updated to show additional columns for MariaDB and as discussed during the last team meeting names of some of the pmadb directives were changed.
